The following operators for attributes are supported.

If an operator is leaded by "!", the meaning is inverted. If an operator is leaded by "I", case of the value is ignored. If no operator is specified, all documents with the attribute correspond regardless of the value. STRAND, STROR, STROREQ, and NUMBT take plural parameters separated by space. Range of NUMBT is inclusive of border values. Two or more attribute names can be listed with separated by "," to mean logical addition.

Other Faculties

"[...] per page" specifies the number of shown documents per page. If documents over one page correspond, you can move to another page via anchors of "PREV" and "NEXT" at the bottom of the page.

"clip by [...]" specifies strength of clipping similar documents. It is useful if too similar documents occupy the page.

Each of "[detail]" links in the result is to show detail information. Each of "[similar]" links in the result is to search for similar documents. Each of "[include]" links in the result is to include clipped documents.
